| | CP1 - When cashing winners in a suit play : high card (s) from the short  side first !
 so that you not become cut off from Dummy
 
 
 
| Declarer (W) ♠ -  A    9 7 2
 ♥ -  Q 5
 ♦ - A  9 5
 ♣ - A K J 8
 |   | Dummy (E) ♠ -   8 6
 ♥ - A K J 4 2
 ♦ -   8 7 4
 ♣ -  9 7 3

Play the ♥Q from Declarer's hand first, then cross over with Declarer's ♥5 to Dummy. Dummy wins the trick and can now run off all remaining heart winners. (If Declarer plays his ♥Q on the  2nd heart trick, he can no longer reach the three remaining ♥  winners in Dummy!)
 Here are two more typical card combinations :
 
| Declarer ♦ A Q J
 | opposite | Dummy 3 5 9 10 K ♦
 |  | Play the ♦A and ♦Q in Declarer's hand first. Then lead the ♦J and take it over with Dummy's ♦K.
 Dummy now  can lead  out the  two remaining ♦ winners.
 
 
 |  
| Declarer ♦ A Q
 ♣ 8 4 2
 | opposite | Dummy 3 5 J K ♦
 ♣ A
 |  | Declarer plays high cards from the short side first, but now can not take over his ♦Q with Dummy's ♦K,  for he then will only make three ♦  tricks in total.Declarer must "unblock" the diamond suit, playing his ♦A and ♦Q  first (playing low in Dummy), then cross over to Dummy with a small club to Dummy's ♣A.
 Now Dummy is on lead to cash the remaining two ♦ winners.

 |  | CP2 - Preferred LEADS by the Defence so that Partner's high card is  not captured  by the Defence
 
  With Dummy  on your left : lead through Dummy's strength
 
 
   With Dummy  on your right : lead around to Dummy's weakness
